Climate change

Climate change is a ‘risk multiplier’ not a separate threat.

Just as a ‘1 in 100 year flood’ may happen tomorrow, discussions about climate change that include phrases like ‘will happen by 2050’ do not mean changes will wait until December 31, 2049. Weather is already intensifying, sea levels have been rising throughout most of the twentieth century and the pace is accelerating, and ocean acidification is already affecting marine ecosystems, with implications for winter food for many braided river birds.
